School children get snappy introduction intro to crayfish crisis - 02/07/12

Children from across the region have been learning about the plight of endangered UK crayfish as a series of new school roadshows launches.

The Crayfish in Crisis roadshow highlights freshwater ecology and conservation with a focus on the plight of the native white-clawed crayfish which Bristol Zoo is working hard to conserve.

So far 10 schools in the region have signed-up for a year-long program of education sessions carried out by Bristol Zoo as part of its involvement in the South West Crayfish Partnership.

One of the first roadshows took place at St Katherine’s School in Ham Green, North Somerset, last week (June 26 & 27), where youngsters took part in a range of aquatic-themed games and activities to learn about how they can make a difference and help protect their local waterways.

Games include a large 3D foam river with interactive team games, aquatic invertebrate identification and the opportunity to see a live North American signal crayfish.

The Roadshow has been offered free to schools thanks to a grant from the Heritage Lottery Fund awarded to the South West Crayfish Partnership (SWCP) earlier this year.

The SWCP is a collaboration between Bristol Zoo Gardens, Avon Wildlife Trust, Bristol Science and Conservation Foundation, Bristol Water, the Environment Agencyand Buglife – The Invertebrate Conservation Trust. 

The South West Crayfish Partnership (SWCP) was set up in 2008 in response to a dramatic 70 per cent decline in numbers of  the UK’s only native crayfish species – the white-clawed crayfish - in south west England.

Signal crayfish were introduced to the UK’s in the 1970s for the fishing and restaurant industry. They escaped and have now spread throughout many river systems, competing with white-clawed crayfish. 

Due to this competition and the spread of a disease which is carried by signal crayfish, white-clawed crayfish numbers have decreased dramatically and they are now classified as a globally endangered species by the IUCN (International Union for Conservation of Nature).   

The crayfish disease can be easily spread by people as it can be carried on anything that gets wet in infected water – this can include wellies, walking boots, fishing tackle and nets. Zoo experts are urging people to check, clean and dry any equipment or footwear that gets wet in rivers and lakes.

Rarely harmful to signals which can carry the disease, it is lethal to white-clawed crayfish and can wipe out entire populations in a matter of weeks.Experts warn they could become extinct from Great Britain within the next 30 years and the species is now protected as well as being a UK Biodiversity Action Plan (BAP) priority species.

Notes to editors

Crayfish in Crisis project (South West Crayfish Partnership)

  • South West Crayfish Partnership (SWCP) is a collaboration between the Avon Wildlife Trust, Bristol Science and Conservation Foundation, Bristol Water, Bristol Zoo Gardens,Buglife – The Invertebrate Conservation Trustand the Environment Agency. 
  • The SWCP Crayfish in Crisis project is an on-going project which is currently funded by the BBC Wildlife Fund, the Environment Agency, the Heritage lottery Fund (HLF) and the Pennon Trust.
  • The SWCP was established in response to the severe decline of native white-clawed crayfish in south-west England and is currently running the largest strategic programme of re-homing at-risk populations of white-clawed crayfish to new safe sites.  In addition, innovative captive breeding and education programmes are integrated into the SWCP to support field conservation work.
  • White-clawed crayfish is the only species of crayfish native to the UK.
  • White-clawed crayfish are protected by law, are classified as endangered and is a UK Biodiversity Action Plan priority species.
  • The South West Crayfish Partnership acknowledges and thanks the help of all other parties that have contributed to the project.
  • Among many key messages the SWCP aims to educate waterway users to check, clean and most importantly, to dry, footwear and equipment after visiting our rivers and lakes.  This helps to prevent the spread of waterway diseases, in particular the crayfish plague which is lethal to white-clawed crayfish. 
  • It is illegal to trap any species of crayfish without specific trapping authorisation from the Environment Agency. Trapping also increases the risk of spreading the crayfish plague.
